My reading of this

It's decided to move the Psycho House to a new location on the backlot. (Psycho II director Richard Franklin said at the time, "they built a tour around it so we had to move it to a remote location". The house was rebuilt and about 30 feet of motel was built. The rest was done as a matte painting. If you notice you don't really see much of the Motel in the picture.

was that the house wasn't physically moved, just rebuilt in a new spot. But I suppose it is ambiguously worded.

And not being original (by "hardly any" I was talking about the entire structure) doesn't mean it isn't a noteworthy landmark (though I don't necessarily consider it deserving of extraordinary preservation).
